Influence of Co2+ ions on photocatalytic properties of MgFe2O4 ferrites
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this work, spinel magnesium cobalt ferrites (CoxMg1-xFe2O4, x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9) were synthesized by a sol-gel combustion method. Magnesium nitrate, cobalt nitrate and iron nitrate were used as oxidizers ...
Nanocrystalline SnO2-Zn2SnO4 composite thick films applied as humidity sensors
(Belgrade : Institute for Multidisciplinary Research, 2019)
Starting ZnO and SnO2 nanopowders (<100 nm) were mixed in a suitable ratio and calcined at 1050 °C for 2 hours to obtain nanocrystalline SnO2-Zn2SnO4 composite powder. Structural characterization performed by X-ray diffraction ...
Nanocrystalline iron-manganite (FeMnO3) applied for humidity sensing
(Belgrade : Institute for Multidisciplinary Research, 2019)
Nanocrystalline iron manganite was synthesized using a sol-gel self-combustion method with glycine as fuel, followed by calcination at 900 °C for 8 hours. Structural characterization was performed using X-ray diffraction ...
The potential of hybrid geopolymer composites
(Belgrade : Institute for Multidisciplinary Research, 2019)
Hybrid geopolymers represent a new class of composite materials formed by incorporating organic polymer into a geopolymer matrix. The properties of hybrid geopolymer depend on the addition of organic phase and the starting ...
Optimization of the preparation of novel polymer/clay nanocomposites
(Belgrade : Institute for Multidisciplinary Research, 2019)
Recent advances in material technologies have resulted in the preparation of novel polymer/clay composites with improved thermal, mechanical, optoelectronic/ magnetic properties and increased biodegradability [1]. In this ...
Theoretical and experimental study of polycrystalline phases obtained by the nanometric ZnTiO3 powder sintering
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this study we have combined two research methods: structure prediction of ZnTiO3 using computational SPuDS software, and the characterization of binary oxides obtained from ZnO TiO2 system. Pure nanosized ZnTiO3 (99.5%), ...
Synthesis and application of silica particles for the removal of heavy metals and pesticide residues from aqueous solutions
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this study, the adsorption behavior of silica adsorbents with different morphology and porosity has been examined in order to evaluate their use for the purification of wastewaters containing toxic environmental chemicals ...
